Abstract

A hand knife (20, 120), of the type having a ring-like rotary driven blade useful for cutting meat and other suitable products; a blade housing (24, 124, 224) for a hand knife; and a circular blade (26, 126). The blade housing has a generally circular groove (38, 138, 238) to receive a ring gear portion (56, 256) of the blade while a cutting portion (60) extends from the housing. One arcuate wall portion (38b, 138b, 238b) of the housing is frusto-conical and faces a similarly contoured peripheral portion of the blade ring-gear. In the preferred construction the housing recess is formed by a cylindrical wall that surrounds the ring-gear portion of the blade and by a frusto-conical wall that is encircled by the ring-gear portion of the blade. A blade retainer (28, 128) secured to the handle acts against a radial flange (62, 162) of the blade when tightened, to retain the blade within the groove, and when loosened allows removal of the blade from the housing.
